rose-tinted glasses

I know the whole "must be because I love you" can be viewed as a joke but my man actually "whispered with a look of regret" at being shot down.

He also proceeded to cheat during the game by tampering with the machine to ensure Chuuya would lose the bet and become his dog. He was also stated as being in awe of Chuuya's fighting ability, repeatedly refering to him as "incredible". Dazai also flat out admits to wanting to try out living because "Chuuya convinced" him.

He is even described as having forgotten how to breathe watching Chuuya fight.

Moving on to the events of Stormbringer, Dazai spends too long exposing his obsession with Chuuya, telling the big bad that he spends all his "days and nights thinking about ways to annoy Chuuya".

He further proceeds to insist that Chuuya is human because of how strongly he hates Chuuya and due to a specific word it can be viewed as him saying Chuuya would hate him less if he wasnt human as was stated in the stage play of the same.

Furthermore at the end of Stormbringer he offers to come up with a new plan to give Chuuya an out if he needs one when he has to use corruption as a last resort. And he fully intends on coming up with a new plan within 2 minutes.

In general Dazai does a lot of staring at Chuuya throughout the light novels. On a lighter note Dazai jokes about wanting Chuuya as his personal maid at one point and demands that Chuuya let Dazai look inside his head and know everything there is to know about him.

But then we move onto the dragon head conflict as mentioned in Dead Apple where after making light of an executive's death and getting punched in the face by Chuuya, Dazai is so shaken up by Chuuya implying he's inhuman, he actually pulls strings to try and bring the conflict to an end. He also stops corruption by touching his cheek and pulls Chuuya's head into his lap while he is unconscious after his fight with Shibusawa. The following is from the manga.

Now everyone knows about the whole Snow White and Prince reference but in the light novel its clarified that Chuuya's ability was not affected by the fog and Dazai knew this but he still forces his head down. Even more telling is that Dazai cradles Chuuya's face for no real reason because Corruption had already been nullified when Chuuya made skin to skin contact when punching him in the face.

And of course that was how their expressions are drawn in the manga panel

Then we move to the present day and you have Dazai saying this to Sigma about Chuuya

But then his comment about Gide has him claim the exact same behaviour is romantic in his messed up troll brain

Basically Dazai has a history of staring at Chuuya in awe since 15, "jokingly" confessed at 15 and then got somewhat upset about the rejection, cheated to be able to keep Chuuya as his, repeatedly makes remarks that imply he is vaguely obsessed with him at 16, tends to let Chuuya rest his head in his lap post corruption, has nullified him twice that we have seen by touching his cheek (as per the movie and once as per the ln). Is actively affected by how Chuuya views him (which was shocking to me).

Aside from that he has also talked about Chuuya to the ADA off screen because Yosano knew about Chuuya and his ability (though this could just be a random update about the membera of the mafia to watch out for during meetings) and I heard he talked about Chuuya to Oda in The Day I Picked Up Dazai ln.

This is not counting any of the seriously insane amount of wan content because I dont view it as canon or atleast entirely canon but there Dazai admits to keeping 27 journals detailing things about Chuuya and its an exaggeration of the canon fact that Dazai prides himself in being a Chuuya Nakahara Encyclopedia. It also plays with how close they both actually are with several character refering to them as besties, Chuuya being forced to admit he doesnt actually hate Dazai.

(Oh and this is not even considering just how much Dazai touches Chuuya, like in the manga there is a part where Dazai keeps tugging at Chuuya's hair and refusing to let go while complaining about how much he doesnt want to touch him. Just let go dude...)

So yea, I would not be surprised if Dazai has his vows prepared by the time the last pre defection ln drops. Ofcourse this is mostly a lighthearted joke about Dazai being down bad but in all seriousness, Dazai genuinely cared about and still cares about Chuuya and its made extremely obvious throughout the novels. Its actually worth noting that it was actually Chuuya who seemed to be more vitriolic towards him until the end of Stormbringer where Dazai actually gives Chuuya a choice and shows open concern for Chuuya's needs. Hell Dazai was also the one insisting on Chuuya's autonomy, while he keeps insisting Chuuya is his dog, he hates the idea of people using him like a tool, its why he always gives Chuuya a choice. Chuuya always actively chooses to go rescue Dazai in Dazai's plans of getting kidnapped. Chuuya can always go, "nah, I dont wanna use corruption" but he doesnt because he knows since the events of stormbringer that Dazai will always give him a choice even if corruption seems like a last resort.

Chuuya has good reason for trusting Dazai. Its cause Dazai has in fact proven to him that he can trust him. Its why he went in to fight a dragon despite being told Dazai was possibly already dead.

(And yea I know the current arc would have people go "lol he tried to drown Chuuya, he clearly doesnt care" and you know what? That's so dumb. Dazai tried to drown Chuuya, yes. But we dont actually know what is happening with this arc rn and what he is doing or if Chuuya is in any way involved in whatever he is doing. Dazai said all those things and there was no need for him to say that but the fact that he even remembered several moments they shared, yea no, he was clearly affected by it. Maybe I am wrong and Asagiri decided to yeet out all of Dazai's characterization we saw with his behaviour towards Chuuya in 2 entire novels of his past but IDK I think I'm gonna wait till this arc ends and everything unfolds before making a conclusion about how Dazai is such an asshole he tried to drown his partner.)
